Relative Galactic Position of Sagittarius

Due to its large size and fortunate position in the sky, the region of Sagittarius contains almost one quarter of the matter in our Galaxy.

This busy area of the sky contains many nebulae and star clusters. Near its border with Ophiuchus lies the innocuous star 3 Sagittarii, which lies less than a degree from the centre of our Galaxy.
